We create floor plans especially for the Internet presentation of your real estate. These are optimized in terms of display format, information density, file format and transfer capability. The area calculation for flats takes place according to WoFlV or commercial objects according to MFG.

Due Diligence

Due Diligence means the careful examination and valuation of buildings and technical equipment prior to the purchase or sale of real estate. Above all, the basic criteria of building condition, condition of technical installations, costs for maintenance and operating costs are taken into account. Opportunities and risks of a sale or purchase can be clarified or even visible.

Comprehensive technical due diligence is a central component of our solution portfolio. Regardless of whether you focus on the qualified recording of individual properties or large real estate portfolios, we analyze and evaluate your buildings and technical systems reliably, inexpensively and professionally. We check everything for you at short notice via “quick check” or as a comprehensive due diligence on “acid test”. The result is a solid foundation for your strategic real estate decisions.

All data is transferred to you in a database in order to provide you with qualified evaluations and strategic decisions.
